I found the Trek at a LBS for $699 (180 off MSRP), and the Rockhopper for $725.

Forks are the same, brakes on Trek are better, I think the Trek has all around slightly better components but I've test ridden both and they seem pretty even. I won't be racing or anything but I will be riding pretty hard on singletracks (I'm 6' 200 lbs.) and getting 3-4 feet of air on occasion. I'm pretty decided on the Trek, but I was wondering what you guys thought.

I got the trek 6000 last year and pretty with it. Overall it has treated me well. I just had a problem with the rear wheel (the spokes keep breaking despite all my and my LBS best efforts) but my LBS is taking care of that. Other than that great ride

Thanks zvh, good to know. I ended up going with the Trek. Good price, good components, great brand. Also, I picked up the 21.5" frame, due to recommendation of the guy at the LBS, he said he rode a 19.5" for years and after riding a 21.5" realized it was too small. I'm 6' 200 lbs at 15 years old. I'm only going to grow about 2 more inches at the most. Do you think this frame size will work okay?

I'm 6'1'' 220 lbs. was going to get my 6700 in 19.5 but my LBS told me to get the 21.5. i have short legs and long torso. i trusted him and ordered the larger size. best decision i ever made. I now realize my old bike was way to small. i guess it really depends on your body and what feels right. sounds like that size will work for you.
